Shave off a TransformationMatrix copy if RenderLayer's transparencyClipBox()
https://bugs.webkit.org/show_bug.cgi?id=152119
Reviewed by Simon Fraser.
* rendering/RenderLayer.cpp:
(WebCore::transparencyClipBox): Multiply the transformation matrix returned by
layer.transform() directly into the transform object, instead of first
multiplying them and then copying the result back into the transform object.
